STOPPING MECHANISM FOR CARDlNG-ENGINES.

SPECIFICATION forming part of Letters Patent No. 480,987, dated August16, 1892. Application filed September 2, 1891- Serial No. 404,508- (Nomodel.) Patented in England August 1'7 1889, No. 12,988.

To aZZ whont it ntay concern.-

Be it known that I, ELIJAH AsHWORTH, engineer, of the firm of AshworthBrothers, of the Moss Brook Works, Oollyhurst, Manchester, in the countyof Lancaster, England, have invented certain. new and usefulImprovements in Stopping Mechanism for Car-ding- Engines, (for which Ihave obtained Letters Patent in Great Britain, No. 12,988, dated August17, 1889,) of which the following is a specification.

My invention relates to the means for arresting the movements of certainparts of the carding-engine on the breakage of the sliver, such meansbeing also adapted to prevent overfilling of the can. Previously to myinvention carding-engines have been provided with motions which havestopped the revolu tion of the doffer when the sliver has become broken;but I consider this method to be defective, for the reason, principally,that as the motion of the main cylinder has continued after the dofferhas ceased to revolve the dotfer has become clogged or overcharged withfibers at the point of contact with the main cylinder. To remedy thisdefect and its at tendant consequences, I employ means for arresting thefeed on the occurrence of abreakage of the sliver, the revolution of thedoffer continuing. I employ levers which are sustained out of action bythe intact sliver or by parts acted upon by the sliver, but arepermitted to act when the sliver breaks, and on such occurrence act uponparts which unlock or release one of the side shaft-bearings, so that itcan be moved to carry the bevel-pin i011 out of gear and so stop therevolution of the feed-rollers. For this purpose and to pre ventoverfilling of the can, I prefer to use a modification of the stopmechanism for which British Letters Patent No. 2,252, of the year 1876,were granted to Joseph Dean; but for the purposes of my invention Iemploy part of such mechanism to act upon other parts which release theside shaft-bearing, as aforesaid.

The manner in whichI propose to carry my invention into effect isindicated in the accompanying drawings.-

Figure 1 represents a side elevation of part of the doffer end ofacarding-engine. Fig.2

represents a vertical section of the upper part of the coiler-head. Fig.3 is a View of the side shaft-bearing and releasing motion. Fig. 4 is aplan View, partly in horizontal section, of the coiler and connectedparts. Fig. 5 is a sectional view of the coiler-head.

In order to distinguish the parts which I have adopted or modified fromthe aforesaid stop mechanism of Joseph Dean, I have marked such partswith the letters of reference which corresponding parts bear in theBritish specification of his invention.

In Figs. 2 and 5, 0 is the trumpet-guide, which is carried by the lever19, which is fixed upon the cross-shaft q, and ris a second lever fixedupon the same shaft and connected with the upper end of a wire m. Thelower end of this wire appears in Fig. 1, wherein it will be seen thatthe wire is attached to one arm n of a lever. This arm of the levertends to drop, but is sustained in the indicated position by the wire.The outer end of the said arm is hooked or bent at right angles, thishooked end just clearing a projection Z, which is formed upon theyielding member 72,

of a clutch which is mounted upon the Vertical shaft 1' of the coiler.The other member h of the said clutch is fixed to the shaft, and bothmembers have driving-teeth or projections 70 7a which have inclinedfaces. The part his driven by the part h so long as the resistance tothe revolving of the part it is small, but when there is agreatly-increased resistance the part It yields in an upward direction.Such increased resistance arises from the falling of the arm n of thelever, whereby the hooked end of the said arm is brought into positionto catch the projection Z, and whereby to arrest the revolution of thepart h of the clutch. hen the part h yields upward, as aforesaid, itacts upon a lever g and rocks it upon its axis. The said lever in itsmovement presses upon a finger t upon a loaded detent-lever t and turnsthe latter into position to engage with a stop it upon the lever '12, n,which is then held in position to just clear the projection Z, so as topermit the engine to work until the sliver can be brought through thetrumpet-guide. The slightly-increasedlowering of the trumpet-guide,caused by the passage of the sliver, has the effect of raising the arm na little higher, whereby the stop a is withdrawn from the end of thecatch-lever t, which then moves away from the stop it, as in Fig. 1, andthereafter the arm n is sustained solely by the trumpetguide, actingthrough the lever r and the wire m. These parts as so far described withreference to drawings I do not claim as new.

In Fig. 1, a is the bearing-bracket, in which is mounted .thebearing-block a, which carries one end of the side shaft b. Fig. 3 is aside view of the said bracket and bearingblock, the side shaft appearingin cross-section. in a recess in the bracket, so as to move the drivenbevel-wheel 0 out of gear with its driver 0, as is usual in some cases.When the wheel 0 is thus disengaged, the revolution of the side shaftceases, and as this shaft gives motion to the feed-rollers the feed alsoceases. There is a tendency for the wheel 0 to be pushed out of gear;but, if considered to be desirable, Ishould apply a spring or loadasindicated, for instance, by the dotted lines as, Fig. 3which would tendto slide the bearing-block in the direction which would disengage thebevel-wheels. This tendency is resisted by a detent-lever d, which looksthe bearing-block in position, as seen in Fig. 3. The said lever ismounted upon a fulcrum at d and is formed with a projection 61 whichprevents the sliding movement of the bearing-block. It will be seen thatif the end of the arm (1 be lifted the projection 61 will be drawndownward out of the way of thebearing-block. The said end (1 rests uponone arm e of a lever, which is mounted upon a fulcrum at e. The end ofthe other arm e of the lever is connected by a link f with one arm ofthe lever g. The effect of this arrangement is that when the part itrises the arm 2 is drawn down by the lever g, and the other arm e, bylifting the end d of the detent-lever, effects the release of thebearing-block, so that the side shaft and the feed-rollers are stopped.It will be seen that this stoppage will follow a breakage of the sliverfor the reason that when the sliver ceases to pass through thetrumpet-guideo such guide will rise, whereby the arm n will be loweredand the revolution of the part h of the clutch will be arrested, therising of such part resulting in the stoppage of the side shaft inmanner The bearing-block a is fitted to slide as aforesaid. Ashereinbefore mentioned, the apparatus acts to stop the side shafton thecan becoming full. The arrangement of the parts which act when the canis full is illustrated by Fig. 5. A pin j is fitted to slide up and downin a bearing bored in a swell upon the casting, in which the bearing forone of the drawing-in rollers is formed. The lower end of this pin restsupon the upper edge of the coiler s and the upper end is in contact withthe lever 19, which appears in Figs. 2 and 4. lVhen the can becomes sofull as that the contents lift the coiler s, the pin j is pushed upward,and, by lifting the leverp, eifects the stoppage of the side shaft. Asimilar arrangement was mentioned in the aforesaid specification ofJoseph Dean, but did not appear in the drawings attached to suchspecification; but in my case the feed ceases when the stopmotion isbrought into action through the complete filling of the can. I may insome cases construct the apparatus without this provision for thestoppage of the side shaft when the can becomes full.

What I claim as my invention is 1. The combination of the side shaft Z)of a carding-engine having a laterally-movable bearing and provided witha bevel-pinion c and a driving bevel-pinion therefor, with alocking-detent cl for the laterally movable bearing, and mechanism,substantially as described, whereby the said bearing is releasedautomatically to allow the said sideshaft to move laterally,substantially as set forth.

2. The side shaft 1) of a carding-engine having a laterally-movablebearing for one end of the said shaft, and bevel-gears c c, incombination with a detent cl for the laterally-movable bearing, thelever e to act upon the cletent, a pivoted lever g, having a link f,connecting it with the said lever e, and mechanism, substantially asdescribed, to act upon the lever g to automatically free the detent, allsubstantially as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
